The main thing the Weather Tile is looking for is the device to implement a weather attribute. That triggers the weather tile being rendered instead of a generic thing tile.
It’s looking for a few key attributes:
weather- description of the weather/forecast [required]weatherIcon- reports a Weather Underground or TWC compatible icon idforecastIcon- should report a Weather Underground compatible icon name- The weather tile falls back to this attribute if the
weatherIconis not available
- The weather tile falls back to this attribute if the
city- replaces the device name in the top-left (locationis used as a fallback)temperature- numeric temperature (without units)feelsLike- numeric temperature (without units)wind- in MPHilluminancehumidity- as a percentage (without units)percentPrecip- as a percentage (without units)localSunrise- timelocalSunset- time
If I remember correctly, weather and forecastIcon are the only required attributes. The rest of the attributes are conditionally displayed based on whether or not they are implemented in the device driver.
Edit:
Here’s a visual layout of what each attribute maps to on the weather tile:
